The invention discloses a high-speed train air conditioner air duct flow guide multi-layer micro-perforated plate composite silencer which comprises a first perforated plate, a second perforated plate and a third perforated plate. The first perforated plate is horizontally placed in a high-speed train air conditioner main air duct. The second perforated plate and the third perforated plate are arranged above the two sides of the first perforated plate; the first perforated plate, the second perforated plate and the third perforated plate are all fixedly placed under an inlet of a main air duct of the air conditioner. The second perforated plate and the third perforated plate are used for primarily shunting cold air in wind noise of a high-speed train air conditioner fan, and the first perforated plate is used for secondarily shunting and reducing the speed of the cold air. According to the technical scheme, the air speed of the main air duct of the air conditioner can be effectively reduced, so that air noise is reduced, and the size is small.
本发明公开了一种高速列车空调风道导流多层微穿孔板复合消声器,包括第一穿孔板、第二穿孔板、第三穿孔板,第一穿孔板水平放置于高速列车空调主风道内;所述第二穿孔板和第三穿孔板布置在第一穿孔板两侧的侧上方;所述第一穿孔板、第二穿孔板、第三穿孔板均固定放置于空调主风道入口正下方;所述第二穿孔板和第三穿孔板用于对高速列车空调风机的风噪声中的冷风进行初步分流,第一穿孔板用于对冷风二次分流降速。本发明的技术方案能够有效降低空调主风道风速,从而降低风噪声,且体积较小。
